An independent tuning system for an antenna, a tuning method, and a communication device are disclosed. The independent tuning system for the antenna is applicable to a communication device. The communication device includes an antenna tuner, a tuning driver and a tuning program. The tuning program includes: a storage component, an input component, a matching component, and a tuning component. A tuning parameter corresponding to optimized antenna efficiency is matched according to a tuning parameter input by a user and a graph or curve chart of correspondence information between tuning parameters and antenna efficiency stored in the tuning component. An NV value of the tuning driver is tuned according to the tuning parameter to achieve independent optimized tuning of the antenna.
